DAPOL PLASTIC KIT  Several
can be joined together to cover many tracks

This plastic Gantry comes with three dummy non
working colour light signals.Some
modellers drill a small hole in the centre of each dummy aspect and fit small
LEDs into the holes.Can be quite
effective.Or use ECKON Wall Signal
Kits.ENES10 or 11 or 12 , or

BANNER REPEATER SEMAPHORE SIGNALS

An
illuminated  Centrally pivoted Semaphore arm in a glass case, showing the
indication of the signal

which
may be hidden from view when a train stops at a station platform.

Eg
On lines used by express and stopping trains. The express train driver needs to
see the signal well

before
approaching the station at speed  It could be positioned high in the air if
there are surrounding

buildings.
The stopping train driver can also see the signal as he approaches the
station,but when he

stops
at the platform he cannot see his signal which may be many feet in the air
above the train  So a

Banner
Repeater signal is used so that the driver can see the correct indication of
the signal at his eye level height.

Rotary Switches, needless to say, have a rotary switching movement. They will be
needed when the number of circuits that need to be changed

simultaneously exceeds the capacity of a toggle or
slide switch.

A7,A8,A9 & A10 ROTARY
SWITCHES  Will cover
multiple switching roles where more than two circuits need to be
simultaneously switched - for example if three or four track controllers are
being used for cab control.

This switch can be used to unlatch
relays by momentarily interrupting the power supply

There are
many different power supplies available within the Model Industry.

Please
read all the manufacturers instructions before attempting to connect any power
supply to an electrical device.

Using an
incorrect power supply may damage the product  It may work initially but may
burn out due to incorrect voltage or amperage being used.There are supplies that are DC or AC.The correct one must be used.

Some
products call for the use of Diodes and or Resistors and orRegulators and or Controllers.

 COMMON RETURN: A conductor which is common to more than one part of an
electrical circuit and which forms the return path for the current from these
parts of the circuit. Normally one rail of all sections or circuits
of a layout is chosen as the common rail and current from all these sections or
circuits returns to the power supply through this rail. The other
rail can then be divided into sections or circuits as required.

 CUTOUT: A protective device built into an electrical circuit for the
purpose of switching off the current when the load reaches a predetermined
number of amps. All Gaugemaster controllers and cased transformers
are fitted with these devices on all outputs. They reset
automatically when the cause of the overload is removed.

 D.C. CURRENT: D.C. current flows constantly in the same direction along
its conductors which are termed positive and negative. The polarity
of the conductors can be reversed and the current flows in the opposite
direction. All controlled outputs from Gaugemaster controllers
produce D.C. current which has been converted by the controller from A.C.
current delivered by the transformer.

 FEEDBACK: Feedback controllers create a closed loop between the
controller and the locomotive which senses the load in the circuit and
constantly adjusts the output. This will maintain the locomotive at
an even speed up and down gradients and around curves without altering the
regulator of the controller. Feedback controllers are not suitable
for Portescap or other coreless motors or for poor quality mechanisms
particularly in N and other small gauges.

 INERTIA: See Simulator

 MOMENTUM: See Simulator

 POLARITY: The two directions of current flow, positive (+) and
negative (-), or potential in an electrical circuit.

 PRIMARY WINDING: This is the winding of a transformer which is connected to
the source of supply, normally the mains.

 REVERSE LOOP: A reverse loop is created where a track leaves a circuit and
then rejoins it with the train going in the opposite direction. This
will result in a short circuit unless the section is isolated from the rest of
the circuit. A DPDT switch is then used to reverse the polarity of
the circuit concerned.

 SECONDARY WINDING: This is the output winding of a transformer and is usually
isolated from primary winding. Many transformers have two secondary
windings.

 SIMULATOR: This is sometimes called "inertia" or
"momentum". It allows controllers so fitted to
automatically accelerate a train, allow it to coast or be braked to a
standstill. This is achieved by two controls, a regulator and a
brake and gives more realistic acceleration and braking. In
Gaugemaster controllers it can be switched off to allow the controller to be
operated with standard control.

 TRACK ISOLATION: Track isolation is particularly important with modern
controllers. You should always ensure it is not possible for more
than one controlled output to be connected to the same circuit or section at
the same time. You should similarly ensure that A.C. and
uncontrolled outputs are not connected to a controlled circuit.

 TRANSFORMER: A device designed to change the voltage of an A.C.
supply. All transformers deliver A.C. current and this is converted
to D.C. by the rectifier circuit in a Gaugemaster controller (see also primary
and secondary winding). Transformers are often used to power
accessories on a layout (e.g. Point Motors).

 VOLT: This is the standard unit of electrical pressure, and
indicates the potential difference between conductors in a circuit, it can be
either A.C. or D.C.
